MOWING-MACHINE.

To all whom it may concern:

Be it known. that- I, CHARLES S. 'Laxorox, a citizen of the United States of America, residing at Olne v, in the county of Richland and State of Illinois, have invented new and useful Improvements in Mowing-Machines, of which the following is a specification.

This invention relates to mowing machines, and it has for its object to produce a simple and efficient device for transmitting motion from the traction wheels to the cutting mechanism in such a manner that the power shall be equalized, thus insuring perfect transmission when the traction wheel at one side of the machine moves ahead of or at greater speed than the traction wheel at the usuallv employed, and which have been.

found deficient in that the transmission of power is notequallydistributed at all times, may be dispensed with.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangementand combination of parts which will be hereinafter full described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and'modifications within the scope of the claim may be resorted to when desired.

In the drawing-Figure 1 is a top plan view showing as much of a mowing machine of conventional construction as is necessary to illustrate the invention. Fig. 2 is a sectional view taken on the line 2-2 in Fig. 1. Fig. 3 is a sectional view taken on the line 33 in Fig. 1. v

Corresponding parts in the several figures are denoted by like characters of reference.

The frame 1 of the improved mowing machine is provided with bearings for the axle 2 carrying the traction wheels one of which, 3, isrigid with the axle, while the other traction wheel at is mounted for rotation thereon. The traction wheel 4 carries a bevel gear '5 which is fixed thereon and which faces a corresponding bevelgear 6, the latter being Specification of Letters Patent. PgitenfdiFjebflSi 1913. Application filed January 7, 191;.

Serial No. 601,301,

slidably mounted uponv theax e withwhicli it is connected forrotationbv sen or key or splinefor in anywelllnio wn and-ape proved manner. 1:

Mounted for rotation .i ponithelaxle inter.- mediate the b'evel gears and ,6' -istl1e master wheel? of a compensating "gear; said master wheel being itself in the nature of a bevel gear, that to say. its rim is provided with bevel teeth to mesh with a bevel pinion 8 upon one end of the transmission shaft 9, the

other end of which carries a disk 10 having a wrist or crank 11 connected with one end of a pitmanlQ, wherebvreciprocatory motion is transmitted to the knife of the cutting apparatus.

he master wheel 7 includes diametrically opposite spokes 13 upon which oppositely disposed bevel pinions 14 are mounted for rotation, said bevel pinions being in mesh with the bevel gears 5 and 6 upon the trac; tion wheels and the axle 2, respectively.

The hub 15 of the bevel gear 6 has an annular groove 16 which is engaged by the bifurcated end of a shipping rod 17, the opposite end of which is hingedly connected with a hand lever 18 fulcrumed upon the frame of' the machine and by means of 'which the bevel gear (3 may be moved longitudinally of the axle to place it into or out of engagement with the bevel pinions 1d of the compensating gear. The said shipping rod 17 is disposed in a horizontal plane with the axle of the mower. Stop means of any well known description may be provided to retain the hand lever and the gear wheel 6 in adjusted position.

Fromthe foregoingdescription, taken in connection with the accompanying drawing, the operation and advantages of this invention -will be readilyfunderstood. By making the master wheel is sutficiently large with reference to the pinion 8 upon the transmission shaft, the latter may be driven at the requisite speed without the use of additional gearing. lVhen the traction wheels travel at, equal speed, the motion will obviously be transmitted through the bevel gears 5 and 6 to the master wheel 8 through the pinions 14 which remain stationary with respect to the wheel 7 as long as the traction wheels move at equal speed. When the speed of the traction wheels for any reason becomes irregular or uneven, the compensating gear including the gear Wheels 5 and 6, the 'pinions 14 and the maste g wheel an axle journaled therein, a traction wheel' disengaged from the pinions 14 which latter will then be rotated idly by the action of the gear wheel 5.

Having thus described the invention, what is claimedas new, is

A mowing machine compnsing a frame,

fixed to the axle; atrac-tion wheel journaled upon the axle, a beveled gear wheel fixed directly-to the side of the journaled traction 15 wheel, a beveled gear wheel slidably mount the said gear wheels ed upon the axle, and arranged to rotate in unison with the. same, a compensating gearmechanism mounted upon the axle between a second shaft journaled in the frame and operatively connected with said compensating gear mechanism and adapted to be operatively connected with the cuttlng apparatus of the mower.

In testimony whereof I afix my signature in presence of two witnesses. 1
